This SSD review reveals, even among the greats like the Samsung 860 EVO, the ADATA SU800 is nothing to turn your nose at and still manages to be one of the best SSDs on the market. The ADATA SU800 can stand toe to toe in terms of performance with its other contemporaries, and do so at a much lower cost.\r\n\r\nWhy We Like It - ADATA SU800\r\nThe ADATA SU800 128GB SSD is the perfect option for anyone looking to transfer their operating system to a separate storage device, transfer large files on the fly, or completely ditch hard drives altogether. If you need a device with a bit more storage space, compare with our Seagate 600 240 GB solid-state drive review.\r\n\r\nPerformance\r\nThe ADATA SU800 has solid random read write speeds that are on par with the Samsung 860 EVO, but blows the Fantom Drives SSHD out of the water. Average sequential write speeds are 520MB\/s, and sequential read speeds push to 560MB\/s (sometimes a few MBs higher). The ADATA SU800 accomplishes this by utilizing 3D NAND flash memory, like the Silicon Power A55\u2019s TLC NAND technology. Its power largely comes from Silicon Motion\u2019s SM2258 controller.\r\n\r\nSATA interface is on the way out, however. Sure, 6GB\/s is nice, but we\u2019re just now reaching the upper echelon up what SATA III can handle. You can keep an eye on its performance with ADATA\u2019s SSD Toolbox software.\r\nDesign\r\nThe ADATA SU800 uses a common design the majority of SSD\u2019s use. It\u2019s a 2.5 inch SATA SSD with a matte black finish and a sticker of the company logo over the top. There\u2019s four threaded holes to secure it to your PC\u2019s chassis. You\u2019ll find a sticker with its product information printed, which includes its storage size, model number, WWN code, and a warranty code. The ADATA SU800 doesn\u2019t feel cheap in the hands; in fact, it\u2019s a rather solid piece of hardware (no pun intended).\r\nValue\r\nWith how well the ADATA SU800 beside the Samsung 860 EVO, you\u2019re getting a really good deal. It\u2019s only $30 for 128GB, so if you\u2019re looking to store your operating system on an SSD, this is the SSD that can handle it just fine.\r\n\r\nHowever, the amount of storage the ADATA SU800 leaves a lot to be desired. Having 128GB is nothing if you want it for more than your OS. That\u2019s why you should turn to its twin brother, the ADATA Ultimate SU800. For general use, the ADATA Ultimate SU800 SSD rocks the house with 1TB and it still costs less than the Samsung 860 EVO 1TB.\r\nADATA SU800 Wrap Up\r\nThe ADATA SU800 performs well beside other SSDs in the same bracket, even better than Crucial\u2019s MX300 in most fields and for a much cheaper price, not to mention the free software you get to keep track of its performance. While 128GB is really small, you can purchase its Ultimate SU800 brother, a 1TB SSD, for $110, which is $60 cheaper than the Samsung 860 EVO 1TB. Its SATA interface does have some latency issues, but what SATA III interface doesn\u2019t? Regardless, what you get in return is one of the best SSDs today.
